                      Temperature Range: Overview of Self-operated Temperature Regulating Valve at 35 ~110


                      Self-operated temperature control valves do not need external energy-saving control valves for temperature control of various heaters in non-corrosive gases and vapors. Using bellows and springs as pressure balancing parts, it has high sensitivity, low noise and reliable performance. Suitable for non-corrosive liquids, gases and vapors. Temperature control in various heating or cooling systems. When the temperature of controlled medium rises, the control valve closes or opens.


                      Design features

                      1. It has pressure balance function, good sensitivity, high control precision and wide adjustable range.

                      2. Low noise, reliable performance and maintenance-free

                      3. Using standard modular design

                      4. Imported fixed-point regulator with reliable quality and over-temperature protection function

                      5. Multiple combinatorial control can be implemented by means of composite components.

                      Self-operated Temperature Regulating Valve Cover

                      Installed with pressure balancing mechanism, 316 bellows + 304 balancing spring, the adjusting mechanism and actuator are disassembled and assembled by connecting nuts.


                      Executing agency

                      Temperature controller is the actuator of temperature control valve. It works according to the incompressible pressure of liquid and the pressure of thermal expansion and contraction. There are two types of temperature controllers with different temperature control ranges.


                      Special type

                      For clean working environment, no lubrication is needed.

                      Mode of action: heating type and cooling type

                      Maximum temperature: cast iron: 180 C; cast steel: 350 C
